LUBRICATION AND GENERAL MAINTENANCE
After the first 500 miles running.
Distributor
Remove the moulded distributor cover and
turn
the
engine over by hand, carefully observing that the
con-
tacts in the distributor are fully opened. Check the
gap with an
0.014-0.016-in. (.3556-.4064 mm.) gauge.
If
the setting is correct the gauge should be a sliding
fit,
otherwise the contact breaker should be adjusted. To
carry out the adjustment, keep the engine in the position
to give maximum opening
of
the contacts and slacken
the two screws which secure the contact plate to the
distributor body. Move the plate until the gap is set
to the thickness
of
the gauge and then fully tighten the
locking screws. Recheck the gap.
